DECISION AND ORDER

This case is decided pursuant to Chapter 410 of the Texas Workers’ Compensation Act and Rules of the Division of Workers’ Compensation adopted thereunder.

ISSUES

A contested case hearing was held on June 14, 2010 to decide the following disputed issue:

  1. Is the preponderance of the evidence contrary to the decision of the IRO that the claimant is not entitled to bilateral injection procedure for sacroiliac joint, provision of anesthetic, steroid, and/or other therapeutic agent with/without arthrography for the compensable injury of _______________?

PARTIES PRESENT

Petitioner/Claimant appeared and was assisted by JBT, ombudsman. Respondent/Carrier appeared and was represented by TS, attorney.

BACKGROUND INFORMATION

On _______________ Claimant sustained a compensable injury to his low back. Dr. V requested approval for bilateral injection procedure for sacroiliac joint, provision of anesthetic, steroid, and/or other therapeutic agent with/without arthrography. The IRO doctor upheld the previous adverse determinations.

Texas Labor Code Section 408.021 provides that an employee who sustains a compensable injury is entitled to all health care reasonably required by the nature of the injury as and when needed. Health care reasonably required is further defined in Texas Labor Code Section 401.011 (22a) as health care that is clinically appropriate and considered effective for the injured employee's injury and provided in accordance with best practices consistent with evidence based medicine or, if evidence based medicine is not available, then generally accepted standards of medical practice recognized in the medical community. Health care under the Texas Workers' Compensation system must be consistent with evidence based medicine if that evidence is available. Evidence based medicine is further defined in Texas Labor Code Section 401.011 (18a) to be the use of the current best quality scientific and medical evidence formulated from credible scientific studies, including peer-reviewed medical literature and other current scientifically based texts and treatment and practice guidelines. The Commissioner of the Division of Workers' compensation is required to adopt treatment guidelines that are evidence-based, scientifically valid, outcome-focused and designed to reduce excessive or inappropriate medical care while safeguarding necessary medical care. Texas Labor Code Section 413.011(e). Medical services consistent with the medical policies and fee guidelines adopted by the commissioner are presumed reasonable in accordance with Texas Labor Code Section 413.017(1).

In accordance with the above statutory guidance, the Division of Workers' Compensation has adopted treatment guidelines by Division Rule 137.100. This rule directs health care providers to provide treatment in accordance with the current edition of the Official Disability Guidelines (ODG), and such treatment is presumed to be health care reasonably required as defined in the Texas Labor Code. Thus, the focus of any health care dispute starts with the health care set out in the ODG. Also, in accordance with Division Rule 133.308 (t), "A decision issued by an IRO is not considered an agency decision and neither the Department nor the Division are considered parties to an appeal. In a Contested Case Hearing (CCH), the party appealing the IRO decision has the burden of overcoming the decision issued by an IRO by a preponderance of evidence-based medical evidence."

The ODG provides concerning sacroiliac joint injections (SJI):

Recommended as an option if failed at least 4-6 weeks of aggressive conservative therapy. See the Hip & Pelvis Chapter for more information, references, and ODG Criteria for the use of sacroiliac blocks.

The ODG provides in the Hip & Pelvis Chapter concerning use of sacroiliac blocks:

Recommended as an option if failed at least 4-6 weeks of aggressive conservative therapy as indicated below. Sacroiliac dysfunction is poorly defined and the diagnosis is often difficult to make due to the presence of other low back pathology (including spinal stenosis and facet arthropathy). The diagnosis is also difficult to make as pain symptoms may depend on the region of the SI joint that is involved (anterior, posterior, and/or extra-articular ligaments). Pain may radiate into the buttock, groin and entire ipsilateral lower limb, although if pain is present above L5, it is not thought to be from the SI joint.

Innervation: The anterior portion is thought to be innervated by the posterior rami of the L1-S2 roots and the posterior portion by the posterior rami of L4-S3.although the actual innervation remains unclear. Anterior innervation may also be supplied by the obturator nerve, superior gluteal nerve and/or lumbosacral trunk. (Vallejo, 2006) Other research supports innervation by the S1 and S2 sacral dorsal rami.

Etiology: includes degenerative joint disease, joint laxity, and trauma (such as a fall to the buttock). The main cause is SI joint disruption from significant pelvic trauma.

Diagnosis: Specific tests for motion palpation and pain provocation have been described for SI joint dysfunction: Cranial Shear Test; Extension Test; Flamingo Test; Fortin Finger Test; Gaenslen’s Test; Gillet’s Test (One Legged-Stork Test); Patrick’s Test (FABER); Pelvic Compression Test; Pelvic Distraction Test; Pelvic Rock Test; Resisted Abduction Test (REAB); Sacroiliac Shear Test; Standing Flexion Test; Seated Flexion Test; Thigh Thrust Test (POSH). Imaging studies are not helpful. It has been questioned as to whether SI joint blocks are the “diagnostic gold standard.” The block is felt to show low sensitivity, and discordance has been noted between two consecutive blocks (questioning validity). (Schwarzer, 1995) There is also concern that pain relief from diagnostic blocks may be confounded by infiltration of extra-articular ligaments, adjacent muscles, or sheaths of the nerve roots themselves. Sacral lateral branch injections have demonstrated a lack of diagnostic power and area not endorsed for this purpose. (Yin, 2003)

Treatment: There is limited research suggesting therapeutic blocks offer long-term effect. There should be evidence of a trial of aggressive conservative treatment (at least six weeks of a comprehensive exercise program, local icing, mobilization/manipulation and anti-inflammatories) as well as evidence of a clinical picture that is suggestive of sacroiliac injury and/or disease prior to a first SI joint block. If helpful, the blocks may be repeated; however, the frequency of these injections should be limited with attention placed on the comprehensive exercise program. (Forst, 2006) (Berthelot, 2006) (van der Wurff, 2006) (Laslett, 2005) (Zelle, 2005) (McKenzie-Brown 2005) (Pekkafahli, 2003) (Manchikanti, 2003) (Slipman, 2001) (Nelemans-Cochrane, 2000) See also Intra-articular steroid hip injection; & Sacroiliac joint radiofrequency neurotomy.

Recent research: A systematic review commissioned by the American Pain Society (APS) and conducted at the Oregon Evidence-Based Practice Center states that there is insufficient evidence to evaluate validity or utility of diagnostic sacroiliac joint block, and that there is insufficient evidence to adequately evaluate benefits of sacroiliac joint steroid injection. (Chou, 2009)

Criteria for the use of sacroiliac blocks:

  1. The history and physical should suggest the diagnosis (with documentation of at least 3 positive exam findings as listed above).
  2. Diagnostic evaluation must first address any other possible pain generators.
  3. The patient has had and failed at least 4-6 weeks of aggressive conservative therapy including PT, home exercise and medication management.
  4. Blocks are performed under fluoroscopy. (Hansen, 2003)
  5. A positive diagnostic response is recorded as 80% for the duration of the local anesthetic. If the first block is not positive, a second diagnostic block is not performed.
  6. If steroids are injected during the initial injection, the duration of pain relief should be at least 6 weeks with at least > 70% pain relief recorded for this period.
  7. In the treatment or therapeutic phase (after the stabilization is completed), the suggested frequency for repeat blocks is 2 months or longer between each injection, provided that at least >70% pain relief is obtained for 6 weeks.
  8. The block is not to be performed on the same day as a lumbar epidural steroid injection (ESI), transforaminal ESI, facet joint injection or medial branch block.
  9. In the treatment or therapeutic phase, the interventional procedures should be repeated only as necessary judging by the medical necessity criteria, and these should be limited to a maximum of 4 times for local anesthetic and steroid blocks over a period of 1 year.

The IRO doctor, an MD board certified in pain management and anesthesiology, noted the ODG criteria require documentation of at least 3 positive exam findings as listed in the ODG, but in the information provided Claimant’s physical examination was positive for only two, Patrick’s Test and Cranial Shear Test. Claimant testified in his own behalf but did not offer any exhibits or call any other witnesses. Dr. O provided a records review and testimony for the Carrier supporting the IRO decision. There was no offer of evidence based medical evidence to overcome the IRO decision.

Even though all the evidence presented was not discussed, it was considered. The Findings of Fact and Conclusions of Law are based on all of the evidence presented.
